Abstract
A henna vegetable dye preparation method belongs to the technical field of chemical engineering dye. The method comprises the following steps: selecting henna, smashing the henna to powder by a smashing machine, adding water, heating for dissolution, filtering, and separately storing solid and a water solution; placing the solid in an extraction tank, adding an ethanol solution, and stirring to extract natural dye liquid, wherein the ratio of the solid to the ethanol solution is (1:1)-(1:20), and the dye liquid A can be obtained through filtering; adding the filtered solid into the ethanol solution for extraction and filtration again, and mixing the filtered dye liquid, the dye liquid A and the water solution so as to obtain a dye extract; concentrating the dye extract by a rotary evaporator so as to produce a dye concentrated solution; and allowing the dye concentrated solution to be subjected to high-speed centrifugal spray drying so as to produce natural dye pulvis. According to the method, the raw material source is convenient to obtain, the manufacturing technology is simple, the prepared powdered dye is very convenient to transport, preserve and produce, and the production efficiency is high.
Description
Technical field
The present invention relates to the preparation method of Lawsonia inermis vegetable dye, it belongs to the chemical dyestuff technical field.
Background technology
Raising along with people's living standard, quality of life and living environment are more and more paid attention to, the biological degradation of natural plant dye self energy, do not affect environment, vegetable dye source plant can enlarge plantation, continuous production, and it is applied to textile dyeing, has significant Social benefit and economic benefit.The Lawsonia inermis plant contains pigment, is a kind of good pure natural dyestuff.
Summary of the invention
In view of the defective that prior art exists, the object of the present invention is to provide the preparation method of Lawsonia inermis vegetable dye, make its technique simple, production efficiency is high, easily extracts the natural plant dye with dyeing function.
For achieving the above object, the technology used in the present invention solution is the preparation method of nail flowering plant dyestuff, may further comprise the steps: choose Lawsonia inermis, be ground into powder with pulverizer, add the water heating for dissolving, filter, solid and the aqueous solution split; Solid places extractor, adds ethanolic soln, stirs and extracts natural dye liquor, and solid is 1:1-1:20 with the ratio of ethanolic soln, namely gets dye solution A after the filtration; Solid after the filtration adds ethanolic soln and again extracts filtration, and the dye solution after the filtration, dye solution A and described aqueous solution obtain the dyestuff extracting solution; The dyestuff extracting solution is concentrated by Rotary Evaporators, make dye concentrated solution; Dye concentrated solution through hig h-speed centrifugal spray drying, is made natural dye powder.Described powder is the 10-100 order.Described Heating temperature is 60-80 ℃.Vacuum tightness 0.085 MPa of described Rotary Evaporators, bath temperature is 65-75 ℃.
After adopting such scheme, compared with prior art have following beneficial effect: raw material sources are convenient, and production technique is simple; Be prepared into powder dye, be convenient to very much transportation, store and produce, production efficiency is high.
Embodiment
Following the present invention is described further in connection with embodiment:
